-Your father has to apply for immigration visa in China, and your mother can file I-485 in US. There are two different cases. You can file two I-130 at the same time, respectively, for your parents.
一起交的话,交到哪个CENTER?
-Check this website (please note that the addresses for two I-130 are different if your mother wants to file I-485 together with the I-130):

另外问下我爸在国内,如何通知他打指纹,做体检?要去哪里做?一定是广州吗?家在上海。
多谢了。
